Dose-response relationships or damage functions are reviewed with reference to their ability to predict the benefits of environmental reductions in acid deposition. the multistep process whereby dollar costs are assigned to damage associated with a given cause (e.g. SO2, acid precipitation, particulate soiling) is outlined in the form of a flow diagram. in the discussion, the status of knowledge, unknowns, uncertainties and research needs are noted.

Recently proposed air quality design criteria for heating, ventilation and air conditioning (HVAC) systems for cultural institutions are presented.

Environmental stresses cause the paint layer to crack and flake. To save the paintings from disintegration they often must be reinforced by a lining and the paint layer must be readhered. Traditional lining adhesives (wax-resin or glue) may penetrate the paint layer and change its appearance.

Folding endurance, reflectance, objective color and pH of the systems have been measured as well as reversibility in water and toluene of the adhesives applied to glass plates. None of these adhesive materials is recommended for use in paper conservation on the basis of observed properties upon accelerated aging. Conclusions reached on the basis of observations at higher temperatures support results obtained at lower temperatures and longer aging times.

In earlier work we have evaluated the effects of artificial aging on impregnating agents, such as soluble nylon and poly(vinyl alcohols), and the effects of artificial aging on poly (vinyl acetate) emulsions used as adhesives.· · The adhesives tested previously showed preponderantly unsatisfactory results under identical test conditions to which samples are subjected. Tests on the adhesive materials used in this study gave a greater number of satisfactory results under identical test conditions. Some of the data included here have been presented in preliminary form A Our experimental results include data on fold testing, surface, and cold extraction pH measurements; objective color; reflectance; and reversibility (solubility) in distilled water.

Similarly, those responsible for the preservation of cultural property in museums, libraries and archives are beginning to consider more objective decision-making procedures for selecting conservation options. The process whereby sources of risk are identified and quantified forms the discipline of risk assessment while the selection among alternative policies developed in response to that risk is known as risk management. Sources of risk to cultural property are identified and characterized. Examples of risk management for cultural property based on laboratory data, e.g. the setting of light levels for exhibitions are presented
